************************************************************************ IERS Message No. 538 October 16, 2025 ************************************************************************ REFAG2026 - Abstract Deadline Extension to Nov. 2, 2025 Dear Colleagues, Following several requests from colleagues interested in participating in REFAG2026 who have not yet been able to register their abstracts for various reasons, we have decided to extend the deadline to 2 Nov. 2025. Don't miss this opportunity to network with experts in reference frames at our event in Munich. This event is set to be a great success and will establish important milestones for the future determination and use of global and regional reference frames. For abstract submission, registration and more information for REFAG2026 see https://geodesy.science/events/munich2026/ We are looking forward to meet you in Munich! Best regards Urs Hugentobler, Xavier Collilieux, Krzysztof Sosnica, Mathis Blossfeld, Fernand Bale, Maria Karbon, Laura Sanchez, Robert Heinkelmann ************************************************************************ IERS Messages are edited and distributed by the IERS Central Bureau.
